That's too bad you wasted all that time. I saw some of it and I couldn't believe that the History Channel. which I normally like quite a lot was covering such an important topic with such a trashy show. Several times they interviewed people who only now after 40 years are coming forward to claim they saw something. The more likely explanation, that these people are just liars who want ther 15 minutes of fame, was not even considered. Also a lot was made of the existence of a photo of the top and back of Kennedy's head, made during the autopsy, that shows his hair in place and no exit wound. It is already well known that this picture was taken after the flap of skin containing his hair was pulled back over the hole in his skull. One guy was droning on about how this area had a 2D appearance in a stereoscopic image he had viewed and this must be because the photo had been doctored. That it might look flat because there was no skull underneath in the wound area was not even mentioned. The History Channel apparently decided that crummy conspiracy theories would get them more ratings than real, carefully researched history. I have been open to the idea that there might have been more involved than just Oswald, but over the years, a lot of these things just haven't stood up and the theories that I saw presented here were not even some of the higher quality ones.
Actually it makes perfect sense. The assassination team proved that they would kill anyone who knew anything and seemed willing to talk. It's only logical that people won't speak up until they feel safe. Now that most of the conspirators have died, people who know things now feel safe enough to speak. And now we can see who did it.
